To remove a stuck faucet nut, follow these steps:
1. **Gather Tools**: You'll need a basin wrench, penetrating oil (like WD-40), a heat source (such as a hairdryer or heat gun), and possibly a hammer and chisel.
2. **Apply Penetrating Oil**: Spray penetrating oil on the stuck nut. Allow it to sit for at least 15 minutes to loosen rust or mineral deposits.
3. **Use a Basin Wrench**: A basin wrench is designed for tight spaces under sinks. Position the wrench's jaws around the nut and turn counterclockwise. If the nut doesn't budge, proceed to the next step.
4. **Apply Heat**: Use a hairdryer or heat gun to apply heat to the nut. Heat can expand the metal, breaking the bond. Be cautious not to damage surrounding materials. Heat for a few minutes, then try the basin wrench again.
5. **Tap with a Hammer**: Gently tap the nut with a hammer to break any remaining corrosion. Be careful not to damage the sink or plumbing.
6. **Use a Chisel**: As a last resort, carefully use a chisel and hammer to cut through the nut. Position the chisel at an angle on the nut's edge and tap with the hammer to split it. This method should be used only if you're replacing the nut, as it will likely damage it.
7. **Clean Threads**: Once removed, clean the threads with a wire brush to remove any remaining debris or corrosion before installing a new nut.
8. **Reassemble**: Install the new faucet or component, ensuring all connections are secure and leak-free.
These steps should help you remove a stuck faucet nut effectively.
